Hey guys, so I am really interested in trying a hydroponic grow. I've been looking at how to do it cheaply, and I just want to make sure I understand things.
1. I can take a 5 gallon bucket with a lid, cut a hole in the lid and put one of these guys in there
Amazon product
2. Fill the bucket full of water and nutrient solution (I already have General Hydroponics stuff)
3. Soak rockwool cubes in water
Amazon product and then put that in the bottom of the basket, partially in water, to start my seed in.
4. Cut a separate smaller hole in the lid to put a bubbler in, and to use as a dip stick hole to check water level.
Things I'm confused about -
Do I ever need to dump the water? How do I know if the nutrients are correct? Do I just add more nutrients in the same proportions with any additional water I add to the bucket? Or is there where I would need a ppm meter for something?
How does the seedling not get root rot, being in water full time like that?
How long will the water take, when the plants are mostly grown, to evaporate? I'm kind of looking for something that can support my plants while I'm gone for 2 weeks on vacation this summer.
